i am just getting a black screen anytime i run the game…


Same here


Who else can’t play since some builds?


If you know where your save file is go to, upload the save file and somewhere in the file is the version the save is on. Change it to the current version of the game.

Honest i would remove the ability increase traits, takes away the fun grind of breeding good traits into one or two super breeders when you can find them in the wild after a few upgrades . Other than that good start, still needs fleshing out.

does anyone have a new build code


not mentioned above: with the latest public test build the code ‘add favor’ will add, obviously, favor to your breeding wallet to purchase the still-very-much-the-same set of poses from the futa at the outlook above the Neko area. Also weird pro tip: it may just be my machine but I found that the game runs a little better in 4K than even 1080p at times, and I’m not using some crazy GPU, just a solid GTX 1070 8gb. I do 4K ‘high’ at 60 fps very playable
